A Virtual Prototype Design Approach of the Embedded Hybrid System

In this study, a novel approach designing virtual prototype (VP) of FCS (namely FCS-VP) for the requirement of rapid and reliable development of FCS of UAV based on statemate technology is proposed. The hierarchical function model of FCS is set up with activity-charts after introducing FCS behaviors, and at the end of this paper, a hardware-in-the-loop simulation testbed for FCS-VP is built. Results of experiments show that a mini-scale, highspeed real time simulation system can be made with the lowest investment, without any loss of system performance, and at the same time simulation environment can provide both intuitive interface and verification/validation to control system design. It is obviously that the research breaks a practical way for the engineering implementation of complex embedded systems and the application of VP in control systems, and is much worthy of applying and generalizing.
